Letters Patent No. 93,641, dated 'August 10, 1869.

IMPROVEMENT HARYESTERS.

The Schedule. referred to in these Letters Patent and making part of thesame.

To all 'wh-om Iit nul-y concern Be it known that we, GLEAN'VrHUs A.REED, of Madison, Dane'county, and JAMES M. CAMPBELL, of Beaver f Dam,in the county of Dodge, and State of Wisconsin,

have invented certain new and useful Improvements in Machines forHarvesting Grain; and we do yhereby declare that the following is afull, clear, and exact vdescription thereof, reference being had to theaccompanying drawings, making part of this specific-ation, and to theletters of reference marked thereon, like letters indicating like partswherever they occur.

`Toenable others skilled in the art to construct and use our invention,we will proceed to describe it.

Our invent-ion relates to machines for cutting or har vest-ing grain;and consists inI a novel construction of the mechanism for operating thesame, and in a peculiar method of constructing and operating the rake,lfor removing the grain tiom the machine, all as hereinafter' more fullyexplained.

Figure 1 is a top plan View of our machine complete;

Figure2 is a side elevation of the same; and Figures 3,y 4, and, areriews of portions shown more in detail.l Our machine is of that classknown as single-wheel machines; and Wev construct the frame of twosidepieces, A, united at the front by a short crossibar, and at the rearby a longer bar, .Y,'which latter projects ont at one side to the widthof the platform, as shown in iig. 1, `anti forms the linger-bar ofthemachine, the main frame being nearly tliangular in form, with its apexforward. f

There is also another cross-bar, Q, reaching from one to 'the other ofthe side-bars A), located a short distance in fmnt of the finger-bar Y,to forma bearing for the crank that operates the sickle, as representedin fig. 1.

' Within this triangular frame is mounted the bear- I ling-wheel B, uponan axle, D, having its-bearings upon the side-bars A, and loosely uponthis same axle is mounted another wheel, C, of less diameter, whichlatter has arranged upon its periphery a series of -pins, e, standingalternately in zigzag forni, at uniform distances apart, as' shown inlig. l'.

A sliding clutch, L, is placed on the axle D, othe inner side of wheel.13, with arms o, which extendI ilnatically slide back and release itshold on thehvhecl C, there being a 'spiral spring on the axle to throwthe clutch in when the machi-ne moves forward.

It' desired, there may also be a lever arranged to operate the clutch byhand, and instead oft-11e spiral spring, a weight or spring may beapplied to the lever, to shove the clutch in.

The sickle I is arranged at the fi'ont of the platform l, in the usualmanner, and is connected byapit'manj, 11, to a rock-shaft or oscilla:ing crank-rod, T, mounted" on the cross-bar Q, as represented in fig.1.

The opposite end of this shaft l is bent at right angles to the crank,and is split, or formed with two arms, n, which latter are so locatedthat as the wheel O revolves, the pins e on its periphery shall strikefirst against one of the arms 1I, rocking the shaft in one direction,and then another ot the pins shall strike against the other arm a on theopposite side, rocking the shaft T in the other direction, thusimpart-ing to the sickle I the requisite vibratory motion.

This crank-rod or shaft T, with its cra-nk and arms', we forge of asingle solid piece, so that there shall be no joints to give or becomeloosened.

Upon the Vend ofthe axle which extends out beyond the side of the frame,as shown in fig. 1,we secure another wheel, E, having a series 'of pins,e', on its periphery, arranged the same as.those on wheel C; and justin'rear of this `wheel we mount, in suitablesupports, a vertical shaft,N, to the lowerV portion of which is rigidly atiixed a 'forked arm, a.,which is operated by the pins e in thesame manner as the crank-shaft T,previously described.

To the upper end of the vertical shaft )I is secured, ligidly, a rod, F,as represented in iigs. l and 2, and from the outer end of this arm orrod F extends a rod, b, having its opposite end pivoted to the rake H,for the purpose of imparting motion thereto.

The rake consists of a ypiece of board or bar, H, connected by a jointat its .re'ar end to a swinging arm, J, which lat-ter is pivoted, at itsrear end, toa bar, G,

vthere beinga brace or bar, f, projecting backward from the platform tosupport and hold the -bar G firmly in position.

The fra-ke H is'slotted, as shownin figs. 2 and 3, and is supported andslides on a guide-rod, O, secured to the 'rear side of the platform, asrepresented in gs. l,

and 2.

A guide-block or cleat, y, is secured upon the face there is secured ametallic piece, t, which has a shonL der projecting a little below thelower face of the rake, so that when it is shoved around behind theguide g it will engagea-gainst the same, and thus serve to guide therake in its forward motion to the front ofthe platform, preparatory toits sweeping off the grain.

Upon the platform 1 there is also secured a springstop, on, asrepresented in figs. 1 and 3, for the purposel of preventing the rakefrom returning across the platl'ornr in the direction in which it carne,this stopjm being arranged to yield and let the rake pass over it as itsweeps the grain oit, and then spring up behind the rake, and prevent itfrom passing back in the same line.

Witlrthe parts thus constructed and arranged, it will be seen that asthe wheel E revolves the pins thereon will impart to the shaft N and itsarm F a reciprocating motion, at intervals, more or less frequent,according to the distance apart ot' the pins As the arm F is thrownaround, as shown in red, the rake 1l', which is prevented from slidingback across the platform by the spring-stop m, is caused to slide backuntil its i'ront end passes behind the stop m, when it is shoved acrossto the opposite side of the piatforrn, as shown in red in fig. 1, theshoulder ou the metallic point t passing around behind the guide g, whenthe return-motion of the amr F, pulling on the rear portion of the rakeH,`causes its front end to slide forward along the guide g to the frontof the platform, from whence the rake is drawn bodily across theplatform, sweeping the grain along with it, and delivering it at theedge, behind the main frame.

By this method of constructing a. machine, We produce one that isexceedingly simple and compact, there being no gear-wheels, and but veryfew parts to wear or get out of order.

As shown in g. 1, we unite the tongue U to front inner corner of themain flame, by a hingejoint, y, and provide a strong hook, 7|, to holdor' lock it rigidly in position when in use. This arrangement of thetongue serres to relieve the machine, more or less, ot' side draught,and the joint. permits it to be doubled back out of the way when it isdesired to store or ship the machine, and still be always attached remlyfor use when desired. ^Having thus described our invention,

'What we desire to secure by Letters Patent, is

1. The'cornbiuation of the tread or bearing-wheel B, loose wheel G,provided with the pins c, clutch L, and crank-rod T, all constructed andarranged substantially as described, l

2. The rake H, jointed to the pivoted rod J, supported on the guide-rodO, and guided in its movements by the stop m and guide g, or theirequivalents, substantially as herein set forth.'

3. lhe arrangement of the wlreel-E, shaft N, with its arms a and F, androd b, for operating the rake, as herein shown and described.
